The Photon SL continues Guru's tradition of incredible road performance and cutting-edge engineering. Knowing that breathtakingly low weight is nothing without stiffness, Guru fortified this high-modulus carbon masterpiece with superb power transfer and world-class efficiency. However, the carbon is also tuned in all the right places for a smooth, sublime ride with vertical compliance and vibration damping to spare. At the root of this frame's gram-for-gram supremacy is the use of North American-sourced, military-grade carbon fiber, meaning the Photon SL tips the scales at under 750 grams for a 54cm. To up the ante even further, Guru includes a featherweight ENVE carbon fork, so you can rail corners with aplomb and speed straight as an arrow in even the most hectic sprints. This model includes a stunning Shimano Ultegra drivetrain matched to hill-topping Shimano RS21 wheels. Rider contact points are covered by a supportive Prologo saddle and Ritchey WCS components for excellent ergonomics and rider comfort.
